I've always liked David's work, but I have to disagree here. There is a huge difference between using an inbox and a to-do list for to-do management: namely, the power to defer items into the future. I write about this in my book Bit Literacy, but there's a good summary on my Lifehacker post about to-do lists.

I recently spotted a Dalek cake in an Oxford, UK bakery - photo here:

I'm impressed you figured out all the different ways to convert and transfer content - it's not well described in the user guide or in the main Kindle pages online.

But overall I think the device is quite good for a first release. Kudos to Amazon.

If you're interested, here's my customer experience review of the Kindle.

Ji Lee's Bubble Project was excellent. Here's a video clip of Ji talking about it at my Gel conference in 2006.

You might also consider Honest Tea's news and co-founder Seth Goldman's response. It's a rich topic.

Keymaps aren't everything - people should be using a bit lever, too (Typeit4me for Macs, Activewords for Windows) - to correct misspellings and expand common words. Your typing speed will go way up, and wrist load goes down.

But the keymap is important. Dvorak cured my RSI, and I've seen it cure the RSI of several coworkers who converted from Qwerty to Dvorak.

As for typing speed - you can find studies to support just about any position. But c'mon. Putting key vowels on the home keys certainly doesn't slow anyone down.

The benefits of Dvorak and bit levers are extolled in my book Bit Literacy, so I hope there are some readers out there who have switched over, too.

SEO = usability?

Two words...

Per line...

To say...

Indexing, great...

And yet...

Whence users?

Jason beat me to it: sounds just like Cool Hand Luke.

It's a very important idea that I hope software developers will pick up on soon. "Letting the bits go" is the only way to survive in what will become an even *more* saturated environment in coming years.

I know GTD works for some people, but I know many other people who find it overly complicated. I'm biased, but I'd recommend Bit Literacy instead - which Mark Frauenfelder wrote about here. It's my book on managing email and information overload, and unlike GTD it's based in bits - not in paper and file folders.

Even the unicorns will look nicer! Nice work, BB team!
